Synthetic benchmarks showed that overclocking our Core i5 6500 to 4.51GHz produced faster results than a 6600K running at an almost identical 4.5GHz. However, gaming benchmarks produced more variance.
Meanwhile, as expected, the dual-core i3 6100 drops back from the pack significantly, though the 4.4GHz overclock we achieved there throws up some interesting results - it offers around 85 per cent of the performance of the Core i5 6500, which makes us wonder how it would compare with the stock performance of the base-level i5 6400, which operates at a significantly lower clock-speed.
So we went back and re-benched the Core i5 6500 still further, keeping it at stock frequencies and running our Corsair Vengeance DDR4 at 2133MHz, 2666MHz, 3066MHz and 3200MHz - and for the 4.51GHz overclock, we also benched there at 2632MHz and 3196MHz (the closest we could get). Pay particular attention to Crysis 3, GTA 5 and The Witcher 3, where more of the benchmark sequences are CPU-bound. Processor frequency produces higher results here, not faster RAM. However, elsewhere, there are some fascinating results.
We'll zero in on one test in particular - The Witcher 3 - as a highlight. Comparing 2133MHz to 3066MHz, there's an 18 per cent average improvement without overclocking the CPU at all, rising to 21 per cent on the all-important lowest recorded frame-rate. Comparing the stock/3066MHz DDR4 result there with the 4.51GHz/2632MHz reading in the table reveals that memory bandwidth is actually more important there than overclocking the processor. Only by pairing the overclock with 3200MHz DDR4 do we actually push that result on. Now, results may vary with different latency timings on the RAM, but the main takeaway here is clear - more memory bandwidth can make a difference.
Intel maybe didn't plan for things to happen this way, but the Core i5 6500 is a highly compelling buy for gamers. The unofficial overclocking has obviously received plenty of attention and can produce blistering results, but even at stock frequencies it's capable of some excellent performance.
Skylake got a lot of legs, but we already knew
Now think about pairing it on servers with an even faster memory.... hmmmm...
More than Jedec standard ram on servers ??? really ??
Current DDR-4 JEDEC standard is 2133MHz at 1.2v and 15CL.
You just post speed migration.
Are you trying to tell me all the 2400Mhz in production and being sold is not JEDEC validated?

Can you find me DDR-4 2667MHz ECC memory for servers and post the link ???
Here's Crucial with DDR4-2400 ECC. That's higher than 2133.
Those are not for servers OR they will not work at those settings, they will revert to 2133MHz 15CL.
Go to DELL, HP etc and every DDR-4 Server is up to 2133MHz.
This was confusing the hell out of me until I went to the linked review and saw that it was the i5 6500 @ 4.51Ghz scoring 8.67Core i5-6600K @ 4.5GHz scored 7.94 @ CB11.5 MT, while Core i5-6600 @ 4.51GHz scored 8.67.
The first jump from 2133 to 2666Mhz yields 2 FPS for 533Mhz.Minimum framerates with different DDR4 speeds:
To fuel the RAM scaling discussion, not only The Witcher 3 but GTA V and Far Cry 4 saw a 15% boost in minimum framerate by going from DDR4-2133 to DDR4-3200 (stock).

nor that five generations worth of Xeons E3 uses standard LGA 115x Sockets.
That's not changing. Skylake Xeons E3 still use the same LGA 1151 socket, just that they demand C Series Chipsets. That is know since the Xeons E3 V5 launch.That's changing in Skylake according to the Anandtech article, so it should be four generations.
It was inevitable, although they seem to be doing it to an extreme form nowadays. That is, segmentation.
